XblocPlus is a single layer armour unit that is recently developed by BAM Infraconsult. It is the successor of the Xbloc. An important advantage of the XblocPlus is the relatively high construction speed compared to the Xbloc. The increased construction speed is caused by the possibility to place XblocPlus in a uniform pattern and the relatively...

Bardawil Lagoon is a tidal lagoon situated at the northern coast of the Sinai Peninsula in Egypt. It’s two artificial inlets, Boughaz 1 in the West and Boughaz 2 in the East, provide a connection to the Mediterranean Sea. They enable the water bodies to interact and support fish migration. Currently, regular maintenance dredging works are...

Worldwide, rubble mound breakwaters are designed and built to shelter and protect coastal areas from overtopping and flooding, especially harbours and shorelines. Rubble mound breakwaters are essential to preserve desired hydraulic conditions within the hinterland, avoiding damage to inhabited or industrial areas. This research focuses on the...

When a breakwater is under heavy wave attack, the concrete armour units will occasionally move, causing a collision between two concrete armour units. This process is called rocking, and induces stresses in the concrete, that may lead to breakage of the concrete armour units. This MSc Thesis provides a probabilistic method to predict breakage of...

Many coastlines feature a sediment transport in a dominant direction, possibly burying a traditional breakwater in sand in several years. The sandbar breakwater concept uses this sediment supply to its benefit to make the use of vast amounts of rocks abundant. During this research the morphological development of the worlds first sandbar...

XblocPlus is a new uniformly placed single layer armour unit, developed by Delta Marine Consultants (BAM Infraconsult). This report focuses on the stability of the first row of armour units, as this row is interlocked less than other rows. When the first row starts to slide, this is a big threat to the stability of the entire armour layer....

During construction of breakwaters, adverse weather conditions can result in damage, in the form of reshaping and loss of material to the open work fronts of the structure. Based on literature research, analysis of work methods, analysis of damage to older breakwater projects and interviews, it was deduced that during construction, the open work...

The design of offshore and coastal infrastructures, sand nourishment and other ’soft’ coastal interventions require the analysis of environmental variables (e.g. wind, waves, rainfall) that can potentially cause the failure of such structures. Processes such as overtopping, beach erosion, and coastal flooding can result from a combined action of...

When designing hydraulic structures, engineers follow a structured and predetermined set of design phases, referred to as the design process. Within this process, the preliminary design phase is a highly iterative process, which requires many calculations. From these calculations many different initial designs of the structure are derived....

Wave overtopping is an important aspect for the design of rubble mound breakwaters. Acceptable overtopping limits are usually based on the mean overtopping discharge or the maximum overtopping volume (EurOtop, 2018). For temporary situations, such as breakwaters under construction, overtopping limits are not clearly defined. This complicates the...

In this thesis, a general method to predict the notional permeability for various structure lay-outs is developed. A numerical model is used to find a characteristic value for different structure lay-outs: the three structures for which Van der Meer determined the P-value, and a fourth structure of which the P-value has to be predicted. The P...

Nowadays, conceptual breakwater layout design mostly relies on experience and expert judgement, making it complicated to demonstrate that an economic optimum has been reached. This stresses the need to develop a tool that is able to establish the economically most attractive breakwater layout for a certain set of requirements and site-specific...

Rapid climate change and the corresponding estimated sea level rise can affect the performance of the coastal defense structures such as breakwaters, seawalls, and dikes. In order to improve these coastal defenses, a detailed understanding of the processes which contribute to wave run-up and overtopping over the coastal defenses needs to be...

Coastal zones have been a dynamic area and most favoured locations utilized for living, leisure, recreational activities, tourism, commerce and many other human activities. Submerged and floating breakwaters have been used as effective systems to protect these zones from wave attack. However, they are only effectively functional if the incident...

A vast majority (84%) of all countries in the world have coastlines and 80-100% of their population resides within 100 km of the shoreline. Studies show a major growth in population in low-elevation coastal zones and a scenario of rising sea level may force millions of people to relocate. To deal with the increased frequency of extreme events...

After the failure of several large breakwaters in late 1970’s and early 1980’s where the role of rocking and breakage of armour became apparent, the importance of understanding this rocking phenomenon is given a great emphasis. Single layer randomly placed armour units are widely used in breakwater designs as they are more economical due to the...

In the present study the stability of crown wall elements on top of a rubble mound breakwaters is investigated. The first step was conducting a literature review, in order to identify knowledge gaps. It was found that current design methods do not take the freeboard of the crown wall into account when calculating the vertical force acting on it....

The international maritime sector accounts for about 2% of all global carbon dioxide (CO2) emissions, the main greenhouse gas that causes global warming. Nations meeting at the United Nations International Maritime Organization (IMO) in London have proposed an initial strategy for the reduction of greenhouse gas (GHG) emissions from ships,...

The Xbloc<sup>Plus</sup> (referred to as Xbloc+) is a new, uniformly placed single layer armour unit, developed by Delta Marine Consultants (BAM Infraconsult). Although a breakwater armour layer with Xbloc<sup>Plus</sup> combines material saving and easy placement with increased stability, the transition between the armour layer and the crest is...

OpenFOAM allowed the author to simulate a large number of scenarios in which the influences of cross-shore profile shape, cobble porosity, cobble diameter and layer thickness on wave overtopping were examined. Four validation runs and six simulations to map the sensitivity are compared with data from two physical experiments conducted in the...
